Stephen hit a couple of problems while merging the last patch in the
directory delegation series, and I found some problems while testing
userland delegations (more fstests forthcoming).
Christian, could you drop the last patch in
vfs-6.19.directory.delegations, and pick up these patches? They should
address all of the problems Stephen reported and make userland
delegation support on files work properly. Let me know if you'd rather I
resend a whole new directory delegation series instead.
